AIM:

1.1 How will you assign Circular section to column?

Introduction:

Column are the vertical member in the Structure that can be of varying size in dimensions
The circular section of column is provided at the upper floor of the building for the better load carrying and access purpose

Procedure:

Create the model in the staad pro that can be a column
Go to properties in that Define parameters
Assign the circular shape of the column
The radius of the circular is given

1.2: How will you assign Unit system to a. std model file?

ANS:

To Assign unit system in the staad pro
Go to file menu and then settings
open the structural settings
Change the dimensions as the required units

1.3: What are the parameters to be specified while using “Bay Frame” option?

ANS:

To create the parameter of the design by Bay frame
By clicking on the Structural wizard option
Click on the frame model option
click on the Bay frame option
Enter the parameters like the length, breadth, height and the bay frame along the length, breadth and height

1.4: Name few codal standards incorporated in STAAD Pro software.
ANS:

In Staad pro the Codal standard is incorporated for Steel, Concrete, Aluminum.
For the Steel the codal provision are IS 800, IS 800: 2007, IS 800:2007 WSD, IS 801
For the concrete Codal provision are the IS 456 and IS 13920 for the Seismic Design

1.5: How will you specify the design compressive strength for an RCC section?
ANS:

Go to the Design option
Click on the define parameter
In the design Parameter the FYLD Compressive strength of RCC section is Given as 25000 KN/m^2

2:1: State the “Input” steps involved in RCC design.

ANS:

Steps Involved in RCC design are

1. Geometry: The Node location and the node spacing are given
2. Properties: Specify the Sectional properties of the section
3. materials: Specify the properties of the material
4. Specifications: The specifications are given
5. Support: The end support is to be given
6. Loading: Need to provide the loading pattern and the loading combination
7. Analysis: Need to Analysis the modal and all the Input Specification are Given
8. Design: Finally, the Design are to be done

2:2: Explain the difference between Fixed and Enforced support condition in STAAD-Pro

ANS:

In STAAD, support displacement loads cannot be applied to such models when the FIXED type of support is specified.
For the ENFORCED BUT type, there is no provision to specify a spring constant.
The only choices, which are built into the program, are - zero stiffness

3:1. Explain the steps involved in analysis of a model using STAAD Pro sequentially.

ANS:

The steps involved in analysis of a model are

Before Analysis the model the load pattern and the load combination are to be provided to the model
Then go to Analysis option
Define Command
Select the data for the analysis of the model by perform analysis, P delta analysis, Nonlinear analysis
It depends upon the support conditions

3.2. Explain the two ways in which a structural framework/model can be created in STAAD Pro software.

ANS:

The two ways to model a structural framework is
1. Creating model by Node by Node
2. Creating model by Bay frame by

3.3. Elaborate the different support conditions in STAAD Pro.

ANS:

3.4. How will you extract the stress distribution for a staircase slab?

ANS:

The Design of Staircase slab is done by Node placement
The creation of plate is used in stair case
BY using Generate mesh
The stress distribution for the staircase slab is done by viewing color in the slab of the design

3.5. Explain the different ways to view SFD & BMD in STAAD Pro.

ANS:

After completion of the Design the staad pro will automatically provide the BMD & SFD
By Entering to the Post processing process click on ok
By clicking the beam results check the shear force Fx and bending moment in Mz

Practical
1. Analyze the following structural elements and validate the results
A. Simply Supported Beam
a. A Simply supported beam with two-point loads symmetrically placed
b. Span L = 20m
c. Load P = 50kN each
d. Both P located at 5m from each support

2. Fixed Beam
a. Span L = 16m
b. Uniformly Distributed Load w=9kN/m

Aim: create the simply supported beam in Staad pro and analysis

procedure:

step-1

Geometry:
